Orientational properties of nematic disclinations.
Topological defects play a pivotal role in the physics of liquid crystals and represent one of the most prominent and well studied aspects of mesophases. While in two-dimensional nematics, disclinations are traditionally treated as point-like objects, recent experimental studies on active nematics have suggested that half-strength disclinations might in fact possess a polar structure. In this a...
متن کاملField-Induced Motion of Nematic Disclinations
An individual defect in a nematic liquid crystal moves not only in response to its interaction with other defects but also in response to an external field. We analyze the motion of a wedge disclination in the presence of an applied field of strength H . We neglect backflow and seek steadily travelling patterns. The stationary picture yields a semi-infinite wall of strength π, bounded by the de...
متن کاملPrediction of disclinations in nematic elastomers.
We present a theory for uniaxial nematic elastomers with variable asphericity. As an application of the theory, we consider the time-independent, isochoric extension of a right circular cylinder. Numerical solutions to the resulting differential equation are obtained for a range of extensions. For sufficiently large extensions, there exists an isotropic core of material surrounding the cylinder...
متن کاملMinimizers of disclinations in nematic liquid crystals
In this work, we revisit the important problem of disclinations for nematic liquid-crystals in the variational theory of Oseen-Zöcher-Frank. Using the framework of dynamical system theory, the Frank’s energy functional among a class of special director fields for both the elastically isotropic and anisotropic cases are examined. The existence result on the critical points of the energy function...
متن کاملSurface disclinations in nematic liquid crystals
2014 It is shown that in nematic liquid crystals the disclinations which are attached to the external boundaries of the specimens can be described by a Peierls-Nabarro type model known from the theory of crystal dislocations. Mathematically, dislocations with planar cores and surface disclinations are then completely analogous if the isotropic one-constant approximation and a planar distributio...
